Description

[Detailed explanation of the idea] The present invention relates to a volatile liquid dispensing device.

In recent years, there have been many developments in the field of air freshener products that emit fragrances into the indoor atmosphere, and various products have come under the names of so-called air fresheners, room fragrances, etc. various dispensers
) is provided filled with.

Among these air freshener dispensers, wick-type ones have a problem in that when the liquid level of the air freshener in the container becomes low, the ability to absorb the air freshener decreases and the fragrance dissipates poorly. Even if there is a large amount, it is necessary to replenish the fragrance to raise the liquid level, and since the entire liquid level is open, the more volatile components of the fragrance mixture will evaporate first, resulting in a higher liquid level. The disadvantage is that the aromaticity decreases as the temperature increases.

On the other hand, PressurizedPac
Kaging (so-called aerosol) types are convenient because they spray air fresheners just by pressing down on the actuator, but the environment and contamination of the fluorocarbons used in these propellants have become a problem, and the containers and valves have become a problem. Disposal is a waste of resources, and the problem of waste pollution has arisen.

On the other hand, manual spray devices, especially pressure-accumulating spray devices, do not require a propellant and the fragrance is sprayed by simply pressing down on the actuator, and can be refilled many times, reducing the resource and pollution issues mentioned above. There is growing interest in the issue.

However, the fragrance of air fresheners sprayed into the atmosphere does not last very long, so a manual sprayer is attached to the porous material and the sprayer is operated from time to time to deliver the fragrance to the porous material and soak it into the air. There are some products that allow you to enjoy the fragrance for a long time due to its evaporation.

This device uses a regular manual sprayer,
A portion of the fragrance sprayed from the nozzle permeates into the porous material, but the drawback is that the amount of porous material stored in one spray is not very long.

In order to overcome this drawback, it is possible to directly supply the air freshener discharged by a manual pump device to the porous material and allow it to soak into the porous material, increasing the amount of fragrance stored in the porous material and allowing you to enjoy the fragrance for a long time. A scent dispenser is also provided.

However, many of the above devices are configured to operate the actuator by removing the cap, and then store and hold the porous material in the container, which makes the structure complicated, and it is troublesome to attach and detach the cap. , there is a problem that the external design is subject to structural constraints.

Focusing on this point, the present invention has developed a volatile liquid dispenser with a simple structure, in which a porous material is housed within the actuator itself, and the case and container that cover the actuator are designed as one unified shape. did.

Although the device of the present invention is primarily intended for the dispensing of fragrances, it is obvious that it can be used for any spatial administration of vapors of volatile liquids.

According to the present invention, there is provided a container containing a volatile liquid; a manual pump device attached to the neck opening of the container and having a discharge port facing upward; and a case fitted to the upper periphery of the container, the upper surface of which is has an opening, and a diverging slit is provided in the peripheral wall; an actuator cap that is housed in the actuator cap and has a cylindrical neck and a flange on which the peripheral wall is erected; A lid body that is fitted into and supported by the stem of the manual pump device through a boss hole provided in the center of the ceiling; and a lid body that is housed in the opening of the case, and that has a central concave portion on its lower surface that connects to the top of the neck of the actuator cap. a porous body placed on the flange of the actuator cap; a liquid passage provided between the actuator cap and the lid body; , when the actuator consisting of the actuator cap, the lid body and the porous body is pushed down, the manual pump device is activated and a volatile liquid is discharged, and the liquid flows through the boss hole of the actuator cap and the liquid passage into the porous hole. There is provided a volatile liquid dispenser characterized in that the volatile liquid agent is configured such that the vapor flows into the liquid body and is stored therein, and the vapor thereof is released into the atmosphere through the emission slit of the case.

Hereinafter, a cylindrical embodiment of the present invention will be specifically described with reference to the drawings, taking the application of the present invention to an aromatic agent as an example. However, the container of the present invention is not limited to a cylindrical shape.

As shown in FIGS. 1 and 2, the container 10 containing the fragrance has a cylindrical shape, and has a step 11 formed on the outer periphery of the upper part, and a cylindrical neck opening upward in the center of the upper part. 12 are formed.

A manual pump device 20 is attached to the neck 12, and the manual pump 20 is fixed by a fixing cap 13 which is screwed onto the neck 12 of the container 10 through a gear sket 22 via a flange 21 thereof.

The manual pump device 20 is a known one, and is preferably of a pressure accumulating type as disclosed in Japanese Utility Model Application No. 165312/1985, but is not limited thereto.

A cylindrical case 30 that is continuous with the container 10 is provided above the container 10 .

The case 30 has three, in this case, erected on the inner wall.
The lower end of the rib 31 is fitted and supported by the step 11 of the container 10, and a gap 14 is formed between the inner wall and the step 11.

Further, a trumpet-shaped upper opening 32 is provided in the upper part, and an actuator cavity 33 for accommodating an actuator 40, which will be described later, is formed inside, while a plurality of vertical divergence slits 34 are provided in the peripheral wall. It is being

It is more like 0.

The actuator cap 50 includes a cylindrical neck portion 51 and a circular tray-shaped flange portion 52 having a peripheral wall 52A erected thereon.

A boss 53 is provided downward from the center of the lower surface of the ceiling of the neck 51, and a central hole 54 formed in the boss 53 is fitted and supported by the upper end of the stem 23 of the manual pump device 20, and is supported on the inner wall of the neck 51. The actuator cap 50 is loosely fitted to the outer wall of the fixed cap 13, while the actuator cap 50 is attached to the stem 2 of the manual pump device 20 between the lower surface of the flange 52 and the upper surface of the container 10.
There is a margin for vertical movement equal to 3 working strokes.

Further, as shown in FIG. 2, the neck portion 51 is formed with a radial groove 56 extending from the recess 55 at the center of the top surface 58 and a vertical small protrusion 57 on the circumferential surface. A gap 57A formed between the inner wall of the central recess 62 of the lid 60 and the circumferential wall of the neck 51, which will be in contact with each other, and the recess 55 and the radial grooves 56 allow the manual pump device 20 to pass through the central hole 54.
A liquid passageway is formed from a discharge port (not shown) of the stem 23 to the porous body 70.

On the other hand, although a vertical diverging slit 59 is also provided in the peripheral wall 52A of the collar portion 52, this slit may not be provided.

The lid body 60 has a hanging peripheral wall 61 that connects to the upper opening 32 of the case 30.

Furthermore, air flows from the outside into the actuator cavity 33 through the gap 14 between the case 30 and the container 10 and flows out through the divergence slit 34, and this air flow helps spread the fragrance.

If the manual pump device 20 of this aroma dispenser is a so-called pressure accumulating type, the fragrance remains in the manual pump device 20 even after being discharged, and then the fragrance is immediately discharged by pressing down the actuator 40. .

As is clear from the above, the present invention is designed to overcome the drawbacks of the wick type dispenser, in which more volatile components evaporate first and evaporation worsens as the liquid level drops. The actuator of the manual pump device has a unique structure in which a porous material that stores volatile liquid is housed within the actuator itself, and the case and container that cover the actuator are designed as one unified shape, so it can last for a long time. We have successfully commercialized a volatile liquid dispenser with an excellent design that allows you to enjoy the aroma throughout the day.
